“…The NAA process involves the capture of a neutron by the lead nucleus to give an isotope with a mass number greater by one [23]. The lead nucleus then emits either one or two neutrons and in the process also emits a 7 -ray [39].…”

Recent legislation required the U.S. Department of Housing and Urban Development (HUD) to establish procedures to eliminate, as far as practicable, the hazards of lead-based paint poisoning in any existing HUD-controlled housing. Thus, HUD promulgated a regulation which requires abatement to eliminate lead-based paint poisoning hazards in housing in which the concentration of lead in paint equals or exceeds 1 mg/cm^. The legislation also required HUD to review test methods for measuring lead in paint. The National Institute of Standards and Technology (NIST) was given this task. That review is the subject of this report. Test methods were evaluated based on the following criteria: 1) safety, 2) reliability, 3) accuracy, 4) precision, 5) detection limit, 6) ease of use, and 7)technical skill required to make a" measurement, 8) nondestructive, and 9) cost of an analysis. Methods were separated into two categories: 1) field test methods and 2) laboratory test methods. The laboratory test methods were also separated by whether the sample needed to be in solution or could be analyzed as a solid. None of the potential test methods met all of the desired criteria.

“…Hodson and Lord (53) used AA for the determination of toxic metals in paint scraped from toys. Activation analysis (65) with a 252Cf source was shown to be a reliable nondestructive method for the determination of Pb in paint at levels of 1%. Trace amounts of As, Cd, Hg, Pb, Se, and soluble Ba have been measured in 149 types of organic pigments.…”

This review includes analytical methods of coating interest that have appeared in the literature since the last published survey (112), or were not included in the previous review, and it covers the literature through November 1974. Some selectivity has been exercised to include only those procedures especially pertinent or those, which in the authors' judgment could be adapted easily to analytical coating problems.A number of books on various phases of coating analysis have been published in this two-year period. In previous years, ASTM Standards on paint were included in parts 20 and 21 of the "Annual Book". However, in 1974, all of the ASTM standards on paint and related products were published in volumes 27-29. Part 27 ( 4 ) contains 190 standards of which 37% are new, revised, or changed in status. Part 28 (5) contains 140 standards of which 24% are new, revised, or changed in status. Among the new standards in this volume are a recommended practice for qualitative identification of polymers in emulsions, chemical analysis of phthalocyanine blue and green pigments, and analysis of white zinc pigments. Volume 29 ( 6 ) includes 240 standards, 12% which are new, revised, or changed in status, and contains a new test for aromatics in mineral spirits by gas chromatography (GC).Haken's book, (41), "Gas Chromatography of Coating Materials," covers the GC analysis of a broad range of raw materials and finished coatings. Litchfield published a monograph (62) describing the chromatographic analysis of triglycerides. A book by Crippen (25) emphasized the combination of organic functional group analysis along with GC retention data and solubility studies for the identification of organic compounds, many being of coatings significance. "Experiments in Polymer Science" (21 ) contained experiments for determining molecular weight distribution, morphology, and thermal properties of polymers. Haslam et al. (48) published a second edition of "Identification and Analysis of Plastics." This edition contains a new 80-page chapter entitled, "Instrumentation Methods"; the remaining chapters are similar to those in the first edition. "Gas Chromatography in the Chemistry of Polymers" (10) covered fundamentals of GC, monomer, and solvents analysis. Other chapters deal with kinetics and reactions of high polymer formation, and the determination of unreacted monomers, pyrolytic GC, and the analysis of additives. The GC analysis of terpenes was described in "Advances in Chromatography'' by Giddings and Keller (37).During the period since the previous Coatings Review, very significant advances have been made in high-efficiency liquid chromatography (HELC) using controlled flow at high pressure, continuous detection, and small particle size column packing material. The modes of separation are based on adsorption, partition, ion-exchange, and molecu-Authors have not been supplled with free reprints for free distribution.
